WebWavelength is the distance between corresponding points of two consecutive waves and is often expressed in units of metres—for instance, nanometres (1 nm = 10 −9 metre). WebMost commercially-available QCLs tend to have wavelengths around 4-11μm, but the extremes of commercially available QCLs have wavelengths ranging from 2.63-150μm. 4,5,6 ICLs are similar to QCLs in that they use layered semiconductor structures and quantum wells for mid-IR lasing, but photons are generated through interband rather …
